INTRODUCTION: Persistent or chronic intestinal ischemic injury (i3) can lead to severe malnutrition and acute mesenteric ischemia. Although recommended, revascularization of splanchnic arteries is sometimes unrealizable. MATERIAL AND METHODS: We report a case series of iloprost use in consecutive stable patients with persistent i3 unsuitable for revascularization followed in a tertiary care center. The feasibility of revascularization was discussed and ruled out by a multidisciplinary team, and informed consent was obtained prior to consideration of a vasoactive therapy...

Valeria Silvestri, Giacomo Isernia
Giant cell arteritis ( GCA) is an inflammatory vasculopathy affecting large and middle-sized vessels , specifically cranial arteries derived from carotid artery. Isolated extracranial vessel involvement can occur. Interest in extravascular manifestations is recently increasing because of diffusion of sensitive and specific imaging tools such as 18FDG PET TC . Patients have an increased relative risk of severe infection. Listeria monocytogenes infection risk is increased, and vascular system involvement and graft infection have been, even though rarely, reported...

BACKGROUND: Percutaneous endovascular aneurysm repair (PEVAR) has been increasingly employed in the endovascular treatment of abdominal aortic aneurysms. Furthermore, the percutaneous approach can be used with minimal sedation and local anesthesia in the majority of cases. The purpose of this study is to assess the safety and effectiveness of a "percutaneous first" approach to femoral access for EVAR. METHOD: From 2012 to 2014, PEVAR has been the preferred approach to femoral access for EVAR at our institution...

BACKGROUND: Arterial blood pressure-induced shear stress causes endothelial cell apoptosis and inflammation in vein grafts after coronary artery bypass grafting. As the inflammatory protein type IIA secretory Phospholipase A2 (sPLA2-IIA) has been shown to progress atherosclerosis, we hypothesized a role for sPLA2-IIA herein. MATERIALS AND METHODS: The effects of PX-18, an inhibitor of both sPLA2-IIA and apoptosis, on residual endothelium and the presence of sPLA2-IIA were studied in human saphenous vein segments (n=6) perfused at arterial blood pressure with autologous blood for 6 hours...

OBJECTIVES: Doppler ultrasound (US) has been widely used to evaluate the cervical venous system of multiple sclerosis (MS) patients according to the hypothesis of chronic cerebrospinal venous insufficiency (CCSVI) with contradictory results. Venous anatomy and pathology can be examined with less operator-dependent magnetic resonance imaging (MRI). DESIGN: To assess the inter-observer agreement in measuring internal jugular vein (IJV) cross-sectional area (CSA) in MR-images and to explore the agreement between US and MRI in the detection of calibres of ≤ 0...

OBJECTIVES: Despite advances in endovascular surgery, lower extremity arterial bypass (LEB) remains the gold standard treatment for severe, symptomatic Peripheral Arterial Disease (PAD). With recent changes in healthcare, there has been an increasing emphasis on reducing the hospital length of stay (LOS). The purpose of this study is to identify the postoperative complications, which occur after discharge from hospital, and to find risk factors for developing such complications. METHODS: The 2013 lower extremity revascularization -targeted American College of Surgeons (ACS-NSQIP) database and generalized 2013 general and vascular surgery ACS-NSQIP PUF were used for this study...

INTRODUCTION: Varicose vein (VV) disease is a frequently occurring pathology of the lower extremities. Although the pathogenesis of varicosity development is not clearly defined, the final common pathway leading to chronic venous insufficiency is the development of venous hypertension, which is associated with severe changes in the venous wall. The aim of this study was to clarify the histological and immunohistochemical changes in great saphenous veins in chronic venous insufficiency...

OBJECTIVES: Compared to permanent inferior vena cava (IVC) filters, higher complication rates occur with long-term use of temporary IVC filters. We aimed to identify patient clinical factors at the time of placement that could predict failure to remove a temporary IVC filter. METHODS: A retrospective review was performed of both vascular surgery and interventional radiology prospective databases between December 2008 and December 2013. We analyzed a total number of 1,024 consecutive, temporary IVC filters stratified by whether retrieval was attempted or made permanent...

OBJECTIVE: MicroRNAs (miRNAs or miRs) have been highlighted to be involved in abdominal aortic aneurysm (AAA) with the emergence of recent miRNA microarray profiling studies. miR-516a-5p has been shown to be significantly overexpressed in vascular smooth muscle cells (VSMCs) from human AAA tissues from our previous microarray study, suggesting its crucial association with AAA. In addition, further bioinformatics analysis predicted methylenetetrahydrofolate reductase (MTHFR), which regulates homocysteine (Hcy) metabolism and is proposed to be a risk gene for AAA formation, to be the down-regulation target of miR-516a-5p...

BACKGROUND: Independent risk factors such as age, loss of consciousness, elevated serum creatinine, low haemoglobin and ECG evidence of ischemia have previously been shown to predict mortality after ruptured abdominal aortic aneurysm (rAAA). With an ageing Australian population, we sought to determine if patients presenting with rAAA now had more predictive risk factors for mortality, and whether these factors remain predictive of mortality. METHODS: The records of all patients presenting with rAAA between January 1985 to December 1993 (past era, group 1) and January 2007 to December 2011 (modern era, group 2) were retrieved...
